Co-Cr-Mo alloy grains

特許 権利維持 A Co-Cr-Mo alloy with nitrogen addition composed of 26 to 35% by weight of Cr, 2 to 8% by weight of Mo, 0.1 to 0.3% by weight of N, and balance of Co is subjected to solution treatment and then subjected to isothermal aging treatment holding the alloy at 670 to 830 DEG C. for a predetermined period of time to form a multi-phase structure composed of an [epsilon]-phase and a Cr nitride by means of an isothermal aging effect.
